For the C5 chassis, there was a major change in that the popular S6 sedan was discontinued in the United States. In its place, you got to choose from a few options; if you had to have a S6, Audi would oblige but only in wagon form in 2002/2003 with the S6 Avant. If you had to have a S sedan, your option was to wait until the 2003 twin turbo RS6 launched and pay a serious premium over a standard A6. But Audi had two spiritual successors to the C4 S6. First, you could get the twin turbocharged 2.7T V6 in the A6 sedan and it could be had with a 6-speed manual. A little heavier than the C4 but with a bit more power, performance was very close to the legendary turbo 5. But few remember that there was a 4.2 V8 option on the C4 S6 in Europe as well, and you could even specify your S6 with (gasp!) an automatic transmission. Audi recreated this package as well in the new C5 A6 4.2 quattro, and to make it a bit more special it was given some S6 details. The 4.2, for example, sported lighter aluminum fenders and hood, along with an aluminum front subframe to match it’s alloy V8. A full 1.4″ longer and with 3.5″ of additional track over the standard A6, the 4.2 also gained the door blades that would later be seen on the S cars. It was the defacto S6 sedan that was never offered, though the 300 horsepower V8 was down on power to the S6 motor and only 2/3s the power of the later twin-turbo RS6. Despite the special aspects the A6 4.2 doesn’t seem to enjoy as much as cult following as either the S6 Avant or the A6 2.7T 6-speed. I’ve rounded up two 4.2s to consider today; one with a manual swap and another with quite low mileage. Which is the winner?
While low mileage, pristine condition Porsches almost seem cliche, finding an Audi with not much distance covered just doesn’t happen very often. When it does, it seems to inevitably be a model that no one is particularly excited about. That’s unfortunate, because often those models are quite competent performers, indeed. Growing off of the Audi Space Frame Concept from 1993, the A8 was the replacement for the short lived V8 quattro. Although the V8 had only been in production for a few years when the ASF was built, the Type 44 chassis was already quite old so a replacement was fitting. And Audi really outdid itself, with a modern, clean design based around lightweight aluminum technology. Underneath, the initial A8 didn’t offer revolution but instead built on the technology incorporated into the advanced for the time V8 quattro. Over its life, though, the A8 became a world-class leading sedan with steadily increasing technology and power output. For the most part, though, what most people remember are the post 2001 changes; introduction for the U.S. market of the long-wheel base A8L and sporty S8. That’s unfair to the often unloved and seldom seen early models which were very similar and quite competent in their own right. Running across a 1999 A8 with only 50,000 miles is rare enough that you might not see it again in the U.S. and offers you the opportunity to get into a nearly new top flight executive sedan:
